Is when you are located on a window used on several records (is working when there is a single record to zoom on), with a table which has several ZoomConditions. For testing, I'm using GW, TaxCategory to opened related products
Steps to reproduce :
Create a new window Product / Product Type = Service and ZoomCondition (Sql WHERE "ProductType = 'S'")
Create a new window Product / Product Type = Resource and ZoomCondition (Sql WHERE "ProductType = 'R'")
With this setup, everything is working fine.
If you open ZoomAcross from Standard TaxCategory, you'll be able to open correct windows with correct content.
But if adding a third ZoomCondition (to open a 'default' window ; in my case a lighter version of Product window), it will fail.
When clicking on 'Product / Product Type = Service', the "ThirdZoomCondition" window is opened, not the "dedicated" one.
